That is pretty common, that things slow down when you put the system under heavy load. That system is underspecced for editing almost anything, but it might meet Adobe requirements for installation. Not for using the software in practice however.
Simply said: Get a new system.
I have a MBA as well, and I wouldn't dream of editing on it. Just too underpowered in so many ways. I agree that your solution is to edit on a different machine.
